7th grade math help me pleaseee

Hope this helped C:

Step-by-step explanation:

a) 149

b) 112

c) 18

d) -8   you subtract -14 from -22

e) -3.3   you subtract -2.8 from -6.1

f) -0.16  

convert the fractions to decimals and then add 0.3(3/10) and -0.46(7/15)

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
